    • Amazing pressure washer
Style: Honda GX390 with CAT Pump
This is a professional pressure washer and I would not recommend it for casual home use. But for professional jobs where it’s running all day long it is amazing. East start up and the Honda engine just purrs and never seems to struggle one bit. I did add an hour meter to keep track of my oil change intervals and changing the oil is a breeze. Extremely happy with my purchase. ... show more

    • Zero Stars not an option, Used this for 20 minutes and belt assembly already broken.
Style: CRX420
Review Image by matthew ryan pobiak
Disliked: having only 20 minutes of use before needing first service. apparently, this unit was assembled on a Friday at 4:30 pm. Vendor was less than helpful, which is sad. i could understand if this was a step i missed in the setup, but it was not. Bottom line is, i purchased with the expectation of having a working pressure washer, and now i have to drop it off for warranty work and 1.5 to 2 weeks wait time. Lessons learned: this type of item may best be bought by a local vendor so you can deal directly with them, and maybe, just maybe those vendors would check the systems out before they sell them? ... show more

    • Awesome
Style: Honda GX390 with CAT Pump
I started my own little pressure washing business two and a half years ago. This is the model I wanted but decided to go with the direct drive version because it was $600 less. I wish now that I would have just ponied up the money for the belt driven version. The number one reason is that this model eliminates the variable of the customer’s water pressure from the equation. I attached it to a 26 gallon tank from Northern Tool that can be purchased here on Amazon and it works famously. The belt drive pump sucks the water right out of the tank. I connected the 3/4” outlet on the bottom of the tank to the inlet of the machine using suction resistant poly hose and a Hudson float valve in the top of the tank to control water flow. I haven’t performed any experiments yet but I know I’m putting out more water. Recently, I was doing a driveway with my older, direct drive, unit and the customer told me that, according to his digital water meter, I was only drawing 3.3 gallons per minute. A bucket fill test showed he was putting out close to 6 gallons a minutes from his hose. I was using a 20” surface machine and the job took forever. With this unit, I’m getting the whole 4.0 gallons. If those numbers are similar to other customers, I’m putting out roughly 21% more water. ... show more

    • Arrived Defective and NO returns/replacement
Style: Honda GX390 with AAA Pump
I appreciate the shipping carriers because they placed my package very carefully (CEVA) but after trying to unbox it, I saw some body damage and scratches and when I try to turn it on, there was an oil leakage. I tried contacting Amazon Support and they said thus item is non returnable therefore they cannot solve anything. I asked them for a replacement and they said its too costly for an item to replace and I get that but why send me a defective item then? Now I can't even do anything about it because there's no other route to take besides selling it locally but its defective anyways so now I am down a bunch if money for nothing. Thank you. ... show more

    • Great unit I just got a lemon pump
Style: CRX420
I got a lemon!!! Wasn't packaged well, unit arrived in a cheap flimsy box, was not able to use 2 wheeled dolly to move. Opened the box and rolled it out. read the manual Added the provided oil did as the manual asked and fired it up with my new 20" surface washer and worked great. stopped the unit to attach the wand to do the fence and with the squeeze of the trigger one blast of water then no pressure at all. How frustrating to shut downturn off the water unhook then re hook everything back up. now I have to take it to a certified repair shop and the lead time is at least 1.5 weeks before it can even get looked at. Im sure it is the pump the motor starts and runs great just a bad pump!! ... show more
